Monitoring time-to-detection of recurrent atrial fibrillation in patients with transient new-onset atrial fibrillation detected initially during hospitalization for noncardiac surgery or medical illness

Approximately one-third-of patients with transient new-onset atrial fibrillation (AF) during hospitalization for noncardiac surgery or medical illness will have recurrent AF within 1 year when assessed using two 14-day ECG monitors. The proportion of patients that would be diagnosed with recurrent AF with less monitoring is unknown.
